IWW and syndicalism

I am both a unionist and a capitalist. I have spent 10 years of my career as an involved IBEW member; going to unit meetings, voting, and salting companies. I have spent the last three years as a business owner. I like to think of myself as an ethical capitalist. My employees get paid union wages, which is higher than most companies in my area. The only reason I haven't unionized my company yet is because it doesn't fiscally work as a small, young company. The burden of the cost of labor would destroy my company. I would not be able to compete in any tangible way with my competitors. To give you an idea: the burden per hour of a journeyman electricians union renumeration package is close to $70/hr. In order to support that burden as well as other overhead: building, vans, tools, insurance, bonds, software, phones, office supplies, I would have to bill well over $120/hr. Now the question is: as a business owner, why would I be taking any risk in employing someone if there is no net gain for all the work done in the background as well as getting stiffed on invoices? The other question is: is everyone cut out to be their own employer? What about the people that only have the ability to show up to work and not organize new clients and new work, what do they do? I'm all for living wages, good working conditions, fair treatment, and and and, but what's the benefit to me as an employer for providing these things to an employee?
